Ukrainian opposition lawmakers are collecting signatures to call a special session of the Verkhovna Rada.

"This morning we received signature lists, and now Ukrainian MPs are actively signing them," Batkivschyna faction leader Arseniy Yatseniuk told journalists in Kyiv on Tuesday.

He added that the petition suggests putting to the vote a motion of no-confidence in Prosecutor General Victor Pshonka.

"In order to consider this issue, the opposition needs 150 votes. We have 150 votes both for holding an extraordinary session and putting to the vote a motion of no-confidence in the prosecutor general of Ukraine," Yatseniuk said.

The opposition MPs also proposed to set up during the session a temporary commission to investigate violations of the constitution during the arrest and imprisonment of former Premier Yulia Tymoshenko and former Interior Minister Yuriy Lutsenko, consider the issue of political responsibility of the heads of the Security Service of Ukraine and the Interior Ministry for the involvement of law enforcement agencies in political persecution, as well as the issue of the dismissal of the prosecutor general.

Yatseniuk said the parliament's special session is likely to take place on January 30.
